rust-memory-container-cs VS cross

To fix the problem, smart pointer is the go-to, in this case at least. Someone made a cheat sheet for memory containers, and I thought might be useful to share it here.

With Rc, it was failing as I'm using rayon for multi-threaded rendering and Rc is not Sync (that's what I understand from: the Rust memory container cheat-sheet

I agree with you here, but it's disingenuous to claim that the Cell family are not an intentional and necessary part of the design of Rust's ownership system; I would be interested to see any sort of documentation or RFC commentary that implies otherwise. Even a simple 'Rust 101'-style cheatsheet makes it apparent that they're very much a small but necessary part of the whole: https://github.com/usagi/rust-memory-container-cs

To compile a program with musl on a glibc system you can use cross-rs!

I cross compile to Mac, bsd, windows, etc cross ... Works great for me with either docker or podman.

If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

We are using https://github.com/cross-rs/cross.

There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.

I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.

Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.

Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.

It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
